Abstract
The global economy is increasingly digital. The internet and other information and communicationtechnologies (ICTs) are changing the way individuals, businesses and governments operate. Theirresilience to natural disasters, and their ability to recover in the aftermath, is thus critical to the resilience of the economy. This chapter discusses the impact of climate events on various types of digital infrastructure. It highlights key considerations for governments and digital infrastructure owners to make their infrastructure more resilient, while maintaining affordability of services. We find that digital infrastructure is vulnerable to various climate risks, but that technology choices and network design can improve redundancy and resilience of networks, by design. Certain infrastructures warrant greater ex ante investment in their resilience considering their criticality in the broadband value chain (submarine cables or landing stations) while others could follow repair and recovery options (mobile network antennas, poles, and towers). We conclude with recommendations for the public and private sectors, noting that governments and sectorregulators can improve network resilience, and increase coordination given the distributedownership and governance models in the industry.

Publication Convergence in Information and Communication Technology : Strategic and Regulatory Considerations(World Bank, 2010)This book is a compilation of two recently completed works on the convergence of information and communication technology (ICT) (Singh and Raja 2008, 2009). Since then, convergence, the eroding of boundaries among previously separate ICT services, networks, and business practices, has accelerated and deepened. At the time these reports were written, convergence was already a reality and was picking up pace in low-income countries, as in the rest of the world. Now, as this introduction summarizes, broadband networks are reaching deeper into previously unserved areas. The growing number of people connected to broadband networks are consuming, sharing, and creating new multimedia content and applications. And they are doing this on handheld and portable devices that are less costly and do more than before. All sorts of users, governments, businesses, individuals, and ICT firms, are looking to cut costs while capturing greater value. Taken together, these trends indicate that convergence is set to accelerate even through the ongoing global economic downturn. Countries that enable convergence through appropriate policy and regulatory responses will realize significant benefits in terms of expanded access, lower prices, and greater competition. Chapter two of this book focuses on the strategic implications of convergence and possible policy responses. Chapter three focuses on emerging regulatory practices facilitating multiple plays, or the provision of multiple services, such as voice telephony, broadcasting, and Internet access, by one operator over a single communications network, typically telephone or cable television but increasingly mobile and fixed wireless networks. The book concludes by presenting several best-practice principles for regulatory responses to multiple plays and, to some extent, to convergence more generally. Indeed, the main task for regulators is to remove artificial barriers and restrictions that are remnants of legacy regulation, thus clearing the way for market forces to play out, promoting the public interest, and leading to the realization of a range of benefits for users.Publication Connecting to Work : How Information and Communication Technologies Could Help Expand Employment Opportunities(World Bank, Washington, DC, 2013-09)Information and communication technology (ICT) has grown as a sector and now employs millions of people worldwide. The proliferation of ICTs has also helped digitize how people find and do work. The world will need to create over 600 million jobs by 2030 for unemployment to remain at current levels. ICT-enabled employment may help address some of this problem both by creating jobs in the ICT sector and by helping to make labor markets more inclusive, innovative, flexible, and transparent. What can governments do to prepare for these changes and maximize employment opportunities? This paper is a first step in an effort by the World Bank to understand how ICTs are shaping, changing, and transforming labor markets. It explores how governments and other stakeholders might respond to leverage the growth of ICTs to help increase employment opportunities. This paper is structured as follows: section 1 serves as an introduction; section 2 defines the scope, focusing on the types of employment opportunities due to ICT as a sector and as a tool; section 3 considers the impact of the ICT sector on software programming, IT services, and telecommunications; section 4 describes how ICTs as tools empower and include more workers in labor markets; section 5 analyzes the challenges and risks that appear alongside these opportunities; section 6 discusses human capital, infrastructure, financial, regulatory, and social systems that will enable ICT in employment; and section 7 identifies strategic themes for governments to consider as they maximize the gains from ICT's increasing role in the world of work.Publication Building Broadband : Strategies and Policies for the Developing World(World Bank, 2010)This book suggests an ecosystem approach to broadband policy that could help in the design of strategies, policies, and programs that support network expansion, have the potential to transform economies, improve the quality and range of services, enable application development, and broaden adoption among users. To identify emerging best practices to nurture this ecosystem, this volume analyzes the Republic of Korea and other leading broadband markets. It identifies three building blocks to support the growth of the broadband ecosystem: defining visionary but flexible strategies, using competition to promote market growth, and facilitating demand. An important but often neglected building block is demand facilitation. This includes raising awareness about the benefits of broadband and improving affordability and accessibility for the largest number of users. Successful countries have often focused on creating a suite of useful applications that increase the relevance of broadband to the widest base of users. Programs to mainstream information and communication technology (ICT) use in education, health, or government have been common.Publication Enhancing the Livelihoods of the Rural Poor through ICT - A Knowledge Map(World Bank, Washington, DC, 2008-06)The major objective of the study was to come up with illustrative success stories as well as failures to give lessons on ICT interventions in the area of rural livelihoods and their impact in Tanzania. The key issues addressed in this study were: 1) common ICTs used by the rural poor in Tanzania; 2) which ICTs are regarded as attractive by different groups and why; 3) the use of ICTs by different age cohorts as part of their livelihoods strategies; 4) the role of ICTs in influencing the livelihoods of the poor; 5) what effects, if any, does use of these resources have on vulnerability, livelihoods and value of assets; and 6) whether or not ICT services can be improved in relation to their usage and effects. The study also made a comparative analysis of the use of ICTs by different groups based on age, location, gender and ethnicity. This study was conducted for a period of four months from October 2006 to January 2007, in three different districts (Bagamoyo, Moshi Rural and Njombe). The findings from this study reveal that ICTs commonly used by the rural poor in the selected districts are radio, mobile phone and TV. Development of ICTs is a result of a number of interventions by government, NGOs, development partners and the private sector, and this has impacted on the livelihoods of the rural poor. Survey results confirmed this by revealing that ICTs contributed to improving rural livelihoods through improved businesses (17%), increased access to education (3%), ease of communications (50%) and increased access to key information (30%). The output of this study is expected to inform policymakers as well as other stakeholders, such as development partners, civil society and the private sector, on how ICTs can be adapted to help improve the livelihoods of poor individuals, families and communities in rural areas and increase their income opportunities and/or livelihood sources, thereby improving their chances of escaping from persistent poverty. It also documents what has already been implemented in Tanzania as far as ICTs and rural livelihoods are concerned, and the pertinent gaps in terms of improving the livelihoods of the rural poor by using ICT tools.Publication Municipal ICT Capacity and its Impact on the Climate-Change Affected Urban Poor : The Case of Mozambique(Washington, DC, 2012)The objective of conducting this case study on Mozambique is to uncover the pattern of municipal Information and Communication Technology (ICT) impact that may exist in other low-capacity countries with analogous political economy structures in relation to leveraging ICT in public sectors. The study concludes by suggesting measures to link the continent's ICT boom in citizen-based mobile telephony and internet usage with the rapid rise of public sector ICT phenomena as a promising means to plug service delivery gaps. In view of these highlights, this report stands to serve as a valuable resource guide to a wide audience of practitioners, including policy wonks, urban specialists; ICT and climate change enthusiasts, as well as social accountability activists. This report consists of five sections. Section one details the impact of climate change on Mozambique's urban poor while also providing an overview of the country's disaster response system. In view of the decentralization of much of Mozambique's ICT and other resources among municipal governments, section two sheds light on leveraging local government-level ICT towards enhancing urban climate resilience and disseminates awareness on the 'ICT- Action Plan for the Reduction of Absolute Poverty (PARPA)' framework. Section three describes the four ICT tools most widely being used towards climate-change adaptation, while Section 4 seeks to quantify the level to which municipal ICT growth is having an impact on urban climate resilience generally, and seeks to answer the question of whether it is having an equitable impact on the poor. Upon measuring the extent to which urban climate resilience is being enhanced and analyzing differential impact on the urban poor, section five recommends targeted reform in ICT-PARPA framework such that ICT impact is equitable for all communities, and postulates how such reform can be realized.

Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.
